[Case Study] Two-Part Mechanical Seal That Can Be Installed Without Disassembling the Pump

[Case Study] Two-Part Mechanical Seal That Can Be Installed Without Disassembling the Pump

Can be installed without disassembling the pump - 2-part mechanical seal.

In a factory using dozens of large circulation pumps for cooling water, frequent water leaks from the pumps were causing problems. These pumps used gland packing as the sealing material, but the seals were ineffective, leading to water leaks that soaked the surrounding area. The factory's production was busy, making it difficult to stop the pumps frequently, and the large number of pumps, along with the safety risks associated with tightening the packing and adjusting for leaks while the pumps were in operation, meant that these tasks were not being performed. 1. Increased loss of water and costs for recovery and cleaning. 2. Reduced lifespan and damage to bearings and pump failures due to water leaks. 3. Wear on the pump shaft caused by gland packing. 4. Adjustments to rotating equipment while in operation are not possible due to the risk of entanglement. 5. Maintenance requires extensive work using tow trucks and other equipment due to the size of the pumps. We received a consultation expressing a desire to reduce these tasks as much as possible.

Mechanical seal repair: Reduce costs by repairing instead of replacing!

Mechanical seal repair: Reduce costs by repairing instead of replacing!

Mechanical seals used in pumps and other equipment. In fact, they can be restored to a condition almost like new through repairs.

Many companies immediately consider purchasing a new mechanical seal when a malfunction occurs. However, it is not widely known that mechanical seals can be restored to nearly new condition through repairs. Furthermore, there is a significant price difference between purchasing a new one and opting for repairs, leading to considerable cost savings. Our repair service can also accommodate mechanical seals from other companies with a quick turnaround, so please feel free to consult with us.

[Case 1] Mechanical Seal Repair and Regeneration

[Case 1] Mechanical Seal Repair and Regeneration

[Case 1] Adoption case at a gas plant factory

Until now, the mechanical seals used in pumps needed to be replaced at a fairly rapid pace, and we had been replacing them with new ones each time, which incurred fixed costs. We decided to try having the discarded seals sent to our company for repair and regeneration, and it turned out that they could be used at a low cost and were as good as new. This has reportedly led to significant cost reductions.

[Case 2] Mechanical Seal Repair and Regeneration

[Case Study 1] Adoption Case at a Beverage Manufacturer

Due to the mechanical seals used in the pumps being special items, the beverage manufacturer was unable to repair them and had been replacing them with new ones each time. After entrusting them to us, we found that they could be repaired. Additionally, we can accommodate changes in materials, which has allowed for cost savings on new purchases, and we have been receiving regular requests from them.
